THE NATIONAL OASI-I REGISTER COMPANY, OF DAYTON, OI-IIO, A CORPORATIONOF OI-IIO, (INCORPORATED IN 1906.)

CASH-REGISTER.

T 0 all whom it may concern:

Be it known that 1, CHARLES A. LUND- GREN, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements inCash-Registers, of which I declare the following to be a full, clear,and exact description.

This invention relates to cash registers, and has for its object toprovide an accounting machine which will print a sales slip or not asmay be desired, and which will also print on a detail strip.

lVith this and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims and apreferred form of embodiment of which is hereinafter specificallydescribed with reference to the drawings which accompany and form partof this specification.

Of said drawings: Figure 1 represents an end view of the registershowing the check key and sliding check table. Fig. 2 represents avertical sectional view of the register showing the printer settingelements. Fig. 3 is a bottom view of part of the sliding table and thelock operating lever showing the camming strip. Fig. 1 is a detailedview of the printing platen and its operating mechanism. Fig. 5 is adetail rear view of the sliding check table in its normal position. Fig.6 is a detail view of the auxiliary platen tripping lever, and Fig. 7 isa side view of the lock operating lever.

It is to be understood that in some of these views ithas been necessaryto omit certain parts of the machine for the sake of clearness.

The type of machine to which these improvements are applied in itsgeneral form of construction is now Well known in the art, being of thetype shown and described in Letters Patent to Thomas Carney, No.497,860, dated May 23, 1893 and No. 683,877, dated Oct. 1, 1901, to bothof which patents reference may be had for a more detailed description.

For the purpose of a better understanding of the description to follow,it may be stated that the specific form of means adopted in the presentinstance for securing the general broad results above outlined,comprises a Specification of Letters Patent.

key operated register having an automatic printing mechanism adapted toprint the amounts of the different transactions upon a strip of paperwhich is automatically fed forward step by step at each operation of themachine and a sliding table upon which a sales slip or a check is placedadapted to be slid toward the machine so as to bring the check to aposition between the printing wheels and the paper strip so that uponthe operation of the machine the check will be printed upon instead ofthe paper strip. The sliding check table is held latched in position forthe check to be printed and the amount keys when depressed are alsolatched. A check key is provided which first releases the sliding table(which is immediately returned to its normal position by suitablesprings) and then operates the printing platen to print the amount uponthe paper strip after which the depressed amount key is released and thedrawer opened.

It will of course be understood that the machine is capable of beingoperated as described in the above mentioned patent-s if it is notdesired to use the check printing devlce.

The same numerals of reference indicate identical parts in all of thefigures.

Referring to Fig. 2 the amount keys 10 are pivoted upon a transverseshaft 11 and when depressed raise a key coupler 12 carried upon a rockshaft 13, and the oscillatory movement of the key coupler reciprocates adouble rack 1a to give a complete rotation to the main operating shaft15 of the machine. On this shaft 15 is a full stroke rack 15 with whichcooperates a pawl 15 in a well known manner. Attached to the rear end ofthe amount keys are lifting bars 16, said lifting bars operatingregistering segments 17 which operate the counters (not shown) and alsomesh with pinions 20. These pinions 20 are in a well known mannerconnected by nested sleeves with the amount printing wheels 21 (seeFigs. 1 and 2). The right hand end of the revolution shaft 15 isextended through to the )rintin mechanism as shown in Fi 1 and carries aplaten operating cam 25 (see Fig. 1) which depresses the platen 26against suitable tension and allows the same to fly up to take animpression from the type wheels.

The paper upon which the various impressions are to be taken comprises astrip 27 which is fed from a supply roll 28 over two guide pins and to astorage roll 29. The inking ribbon 80 is suitably carried by guiding andsupporting rollers to extend between the paper strip and the typewheels. For a more detailed description of this much of the printingmechanism reference may be had to the above mentioned Letters Patent No.683,87 7.

The check table is mounted upon shafts 36 and is adapted to he slid uponsaid shafts toward the machine. Suitable springs 37 are coiled about theshafts 36 to hold the table in its normal outer position againstenlarged heads formed on the outer end of the shafts 36 to prevent thetable from slid ing off said shafts. The table is latched in its innerposition by two spring pressed pawls 38 which are pivoted at 39 and areconnected by a link 40. The noses of these pawls normally bear againstthe under side of the shaft 36 and are adapted to snap into notches 41formed in said shafts, when the table is pushed in. It is evident thatthis will latch the table in its inner position until it is released bythe mechanism which will now be described.

Pivoted at 42 is a check key 43 having a laterally extending pin 44which engages a slot 45 formed in the lower end of a release lever 46pivoted at 47. An upwardly extending arm 48 of the lever 46 is soarranged that when the check table is pushed in the link is in the pathof operation of said arm. If the check key is now operated the pin 44engaging in the slot will rock the lever 46 on its pivot therebybringing the upper end of the arm 48 against the link 40 to trip thepawls 38 from their engaging notches 41 and release the table which willbe returned to normal position by springs 37. To prevent the return ofthe check key after it has been partly operated and to compel a completestroke of said key before it can be returned I provide a toothed plate50 fastened to the side of a downward extension of the check key adaptedto be en gaged by a spring drawn pawl 51 in a manner well known in theart. The slot 52 straddles the pivot of said pawl and serves as a guidefor the check key. A spring 53 secured at one end to the front part ofthe check key and at the other end to the framework of the machineserves to return the check key to its normal position against a stop pin54. The pressing down of the check key operates the printing platen asecond time to print the amount set up by the printing wheels. Themechanism for accomplishing this consists of a lever pivoted on the sideof the check key at 61 and carrying at its upper end a swinging trippawl 62 (see Fig. 6). This pawl is pivoted at 63 and has a downwardlyextending heel 64 to which is attached a spring 65 the other end ofwhich is fastened to a pin on the le ver 60. The heel 64 allows the pawl62 to be moved in one direction freely but limits its movement in theopposite direction. The pawl 62 is also supplied with a tripping nose 66which is adapted to engage a pin 67 having a beveled face and mounted inthe front end of the printing platen 26 (see Fig. 4). The tripping nose66 is brought into engagement with the pin 67 by the engagement of thelower end of the lever 60 with the hub 77 of a lever 78. The lower endof the lever 60 is formed as shown so that during the first part of thedownward movement of the check key it will be cammed toward the front ofthe machine thereby bringing the tripping nose 66 into engagement withthe pin 67 of the printing platen. The continued downward movement ofthe check key will cause the printing platen to be drawn downwardagainst the tension of its spring. Toward the end of the downwardmovement of the check key a pin 68 thereon will contact with therearward side of the lever 60 and rock the tripping nose 66 away fromthe pin 67 and allow the printing platen 26 to fly up to take a secondimpression from the type wheels.

To lock the amount keys 10 in their depressed position and to releasethem by the depression of the check key the following mechanism may beemployed consisting in the present embodiment of means for latch ing thekey coupler 12 in its elevated position until the check key isdepressed. The key coupler is supplied with a laterally extending pin 70which is adapted to rest upon the upper end of a latching pawl 71 whenthe coupler is elevated. This pawl is pivoted to the side frame at 72and has a downward projection 73 on which is mounted a pin 74. The pin74 extends through a slot 75 in the side frame of the machine and isengaged by a short arm 76 which is fast to a hub 77 of a lever 78. (SeeFig. 7.) The upper end of the lever 78 is bent to form a right anglewith the main body of said lever and extends directly under the checktable 35. Mounted in this lateral extension of the lever 78 is ananti-friction roller 79 which is engaged by a camming block 80 secureddiagonally on the under side of the check table 35 (see Fig. Pivoted at81 to the side frame of the machine is a spring drawn pawl 82 whichserves to retain the pawl 71 under spring tension in either of its setpositions. (See Fig. 2.) The operation of this part of the machine is asfollows. I will assume that in this operation of the machine it isdesired to issue a check. The check will be placed upon the table andthe table pushed in. Pushing in the table brings the cam block 80against the antifriction roller 79 and cams the lever 78 rearward. Thiswill force the short arm 76 rearward as it is secured to the hub 77 ofsaid lever. The rearward movement of the arm 76 will cam the pin 7%rearward which pin being fast to the latching pawl 71 will cause theupper end of the pawl 71 v O a to be swung against the pm which is fastto the key coupler. The amount keys are then operated to raise the keycoupler. lVhen the key coupler has reached the extreme limit of itsupward movement the latching pawl '71 will snap under the pin 70 andhold the coupler in its elevated position. The length of the slot '75limits the movement of the pawl 71 in both directions. When the checkkey is depressed while the amount keys are locked by pawl 71 a cammingprojection 90 on the check key will strike the pin 74 and cam it forwardthereby releasing the key coupler and returning the lever 78 to itsnormal position. The check table has been previously released so thatthe cam bar 80 offers no obstacle to the return of lever 78. For thepurpose of keeping the check more firmly on the table I have providedthe table with a guard plate 100 and 011 this plate and directlyopposite the printing line I have formed a pointer 101 which will serveas a guide for the insertion of the check. A suitable opening in boththe plate 100 and the table 35 is provided to allow the printing to bedone.

The complete operation may be described as follows: The check is placedupon the table and slid under the guide plate 100. The table being nowpushed in the pawls 38 will engage in the notches s1 and latch the tablein its inner position. T 1e pushing in of the table also sets thelatching pawl 71 in a position to latch the key coupler in its elevatedposition when the amount key is operated as previously explained. Thetable being in, the amount keys are operated and latched in theirdepressed position by pawl 71. The cam 25 will cause an impression to bemade upon the check. Although the platen strikes the paper strip 27there is no impression taken thereon as the check has been insertedbetween said strip and the inking ribbon 30 thereby receiving theimpression. Now the check key 43 is operated with the following results:The first part of the downward movement of the check key causes the arm18 to trip the pawls 38 and release the table which will spring back toits normal position as before described. By this time the tripping nose66 has come into engagement with the pin 67 and is forcing the platen 26downward against its spring. As soon as the pin 68 strikes the rearwardside of the lever 60 the continued movement of the check key causes thetripping nose 60 to be tripped from the pin 67 thereby allowing theplaten to fly up and make an impression upon the paper strip. At thefinal downward movement of the check key as the camming projection 90 ofsaid key will strike the pin 7d and cam itforward. This will trip thepawl 71 and allow the key coupler to return to its normal position. Thecheck key is returned to its normal position by the spring carrying thelever 60 with it. On the return of the lever 60 the tripping nose 66 ofthe pawl 62 will strike the beveled face of the pin 67 and will wipeidly by said pin.

VVhile the form of mechanism here shown and described is admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow. it
